Corona Hat: A new invention by Dr Sanath Hettige a leading researcher and presidential award winner.
Due to the COVID 19 pandemic, wearing a facemask is compulsory in most parts of the world. However, covering only the nose and mouth is not sufficient. Air borne viral particles could remain on a person’s scalp and hair and be active for a period of time and enter the upper respiratory tract.
So why not wear a hat? Even wearing a normal hat along with a facemask will give added protection to a person’s head and neck from deposit of viral particles. This has not been thought of before.
A new invention, the Corona Hat will give added benefit by destroying the corona virus and possibly enhance the development of immunity to the virus by inhalation of attenuated virus.
An outbreak of pneumonia of unknown origin was first declared on 31st December 2019, from Wuhan City in Hubei Province of China. On 7th January 2020, it was diagnosed and reported as ‘Novel Corona Virus’. On 30th January 2020, the WHO declared it as a Public Health Emergency of International Concern. On 11the February 2020, the WHO renamed the disease as COVID-19 and on 11th March 2020, declared the outbreak as a pandemic with widespread global transmission even before identifying the exact epidemiology of the disease (1).
COVID-19 disease is a viral respiratory tract infection caused by a corona virus. It is mainly transmitted through droplets generated when an infected person coughs and sneezes. These droplets are deposited on surfaces or directly on the face of a person at a close distance. A person could get infected by breathing in the virus containing droplets (2).
An aerosol or airborne virus could get deposited on a person’s hair, scalp, forehead and the neck and remain alive for sometime. It’s a common habit to touch one’s hair or face, or scratch one’s scalp. This causes virus to get into the person’s nostrils and upper respiratory tract and cause the infection. (3).
The incubation period of COVID-19 disease is 2 to 14 days, which is the time period a person would not show signs and symptoms after getting infected. People remain infectious for up to two weeks after they get signs and symptoms, and could spread the virus even if they do not show symptoms (4).
As of date 31st December 2020, the global COVID-19 infected persons was reported as 83,800,241 with a global incidence of 10,751 per million population. The countries with the highest number of reported cases were USA, India, UK, and some European countries, with the highest number of cases reported as 20,451,302 from USA. The total global deaths was reported as 1,825,030 which 234 deaths per million cases (1).
South East Asia, India and Indonesia reported the highest case numbers of 10,286,329 and 743,198 by 31st December2020. Sri Lanka reported 43,299 cases and 204 deaths by 31st December 2020 and was in the cluster transmission stage (5).
Since the transmission is by air borne droplets the only means of stopping the spread of the disease is by isolation or barrier methods.
The only barrier method practiced worldwide is facemasks, which protect only a part of the face but most importantly the respiratory inlets the nostrils and mouth. It is important to note that viral particles deposited on the hair and scalp could also easily reach the nostrils or mouth and reach the upper respiratory tract and cause the disease.
Though surgical caps and other forms of personal protective equipment are been used in special circumstances by hospital staff, a hat or a cap that could be worn in day-to-day life has not been promoted worldwide as a protective from SARS-CoV2 infection. In this regard, this is the first time that the importance of a hat/cap in daily wear has been discussed in the world literature.
The author strongly proposes that regular wear of hat/cap or any form of head ware will reduce the probability of been infected by air borne or droplet transmission.
Further, this hat/cap could be embedded with solutions toxic to viruses but not toxic to humans.
The New Invention
Figure 1. – HAT soaked in anti-viral chemicals
This invention is a head cover, which could be in the form of a hat or a cap, which will protect or reduce the incidence of infection by aerosol or airborne pathogens such as viruses and bacteria.
This hat/cap could be worn during day-to-day activities or as a costume ware that gives protection against infections such as SARS-CoV-2.
The main feature of this hat/cap will be that it will be soaked or embedded in a chemical or chemicals that will be toxic to virus, bacteria or any other disease causing pathogen similar SARS-CoV-2.This patented chemical formula will destroy or attenuate the virus incapable of causing disease.
This hat/cap may have one or more additional metallic copper or a zinc band or bands contacting on the front or back to generate an electric current. This activity could be augmented by fixing a lightweight battery and or an electric circuit to the hat/cap. This is done to produce a static electrical current or an electric filed around the head neck and face to kill the air bone viruses reaching a person.
The hat/cap may contain one or all the above features for additional advantage.
One of the main concerns about face masks is that during their use viral particles could be deposited on the surface of the mask and will not be destroyed as a result when a person meddles with the mask during wear the virus on the surface of the mask could reach his/her nostrils. Anti -viral chemicals should not be embedded on a facemask because the chemicals would be in immediate proximity to the mouth and nostrils with a high possibility of inhalation.
This especially designed hat will contain chemicals that will destroy the virus or make the virus attenuated and incapable of infection. The inhalation of attenuated or dead viral particles could produce some immunity to the infection. Inhaled vaccines are under research (6,7). Extensive research has to be conducted to prove this hypothesis.
Conclusions and Recommendations
A hat/cap would reduce the probability of been infected by SARS-CoV-2 infection because it will prevent the deposition of viral particles on the head and neck regions and subsequent entry to the respiratory tract. Understanding this concept does not need advanced research, as it is similar to the accepted fact that face masks reduce the incidence of COVID-19. Wearing a hat/cap in addition to a face mask will give added protection. I recommend that people wear a simple hat/cap with a large brim during their day-to-day life until such time the more advanced product which would be a patented product would be available in the market.
